Accuracy of Guided Implant Placement Using Double Versus Triple Scan Protocol in Completely Edentulous Patients

Accuracy of Guided Implant Placement Using Double Versus Triple Scan Protocol in Completely Edentulous Patients : Randomized Clinical Trial

16 implant placement by surgical guide using double scan protocol versus triple scan protocol to Evaluate angular and linear deviation of virtual implants and actual implant position in completely edentulous patients according to scanning protocol C1(double scan technique) and C2 (triple scan technique) .

Study Overview

• Status: Unknown
• Conditions: Dental Implantation
• Intervention / Treatment: Diagnostic test: scan protocol

Detailed Description

In this study we discuss linear and angular deviation of actual implant position using planning protocol C1(double scan technique) or C2 (triple scan technique) in completely edentulous patient .

Both protocols C1(double scan technique) and C2 (triple scan technique) indicated in completely edentulous patient and require C.T scan for patient wearing scan appliance .

In C1(double scan technique) , after CT scan for patient wearing scan appliance , two optical scan for the model with and without scan appliance.

In C2 (triple scan technique) , after CT scan for patient wearing scan appliance , CT scan for scan appliance alone .

Teeth positions in both protocols were identified by radio-opaque scan appliance .

16 implant placement by surgical guide using double scan protocol versus triple scan protocol ( two groups - 8 implants in each group ) to Evaluate angular and linear deviation of virtual implants and actual implant position in completely edentulous patients according to scanning protocol C1(double scan technique) and C2 (triple scan technique) .

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
double scan protocol; In C1(double scan technique) , after CT scan for patient wearing scan appliance , two optical scan for the model with and without scan appliance.
triple scan protocol; In C2 (triple scan technique) , after CT scan for patient wearing scan appliance , CT scan for scan appliance alone .	Diagnostic test: scan protocol; Scanning strategy is based on multiple scans. Essentially one CT scan of the patient (usually with a scan appliance). Another CT scan of the model or scan appliance may be required (double scan technique). Such a second CT scan can be replaced by optical scanning of the model and scan appliance (triple scan technique).
